Best Straight Shaft Gas String Trimmer
Best Overall: Husqvarna 128LD
- Easy to start, handle, and use
- Lightweight yet powerful enough to deal with most weeds and grass
- Great bang for your buck
- Convenient to store and transport
- Multiple attachments for optimal flexibility
- Have troubles cutting through heavy weeds
- Too short for some tall homeowners
The Husqvarna Gas Straight Shaft String Trimmer 128LDis the most well-built, versatile, and reliable that can do an excellent job on any medium gardens or home yard.
You don’t have to be a professional to have your hedge kept in shape and redundant branches on your fence cleared.
What makes a world of difference is the air purge technology which not only eliminates air from the fuel system and carburetor but also effortlessly turns on the engine to perform various tasks.
Though the Husqvarna Gas Straight Shaft String Trimmer 128LD works well for most regular uses, it sometimes bogs down in extremely heavy weeds.
Another minor issue is that this curved shaft weed eater might be too short for some tall homeowners.
T25 automatic trimmer head
12.2 x 10.2 x 40 inches
Easy loading T25 semi-automatic trimmer head& manual, multi-purpose, Smart Start recoil system and fuel pump, strong, braided wire cable drive
Husqvarna Gas Straight Shaft String Trimmer 128LD is a straightforward versatile and powerful machine that can tackle any brush, branch, and lawn care with ease.
Budget-Friendly Option: CRAFTSMAN WS205 WEEDWACKER
- Lightweight and easy to use
- More control for less vibration and operator fatigue during use
- Trim much more grass/branches in less time
- 2-cycle engine
Rather than a weed wacker, the CRAFTSMAN WS205 works as a brush cutter. You can mount either a balanced curved shaft on this big bruiser or a bump-feed trimmer head feeding .95 twisted line for a much better view of the area needing trimming.
What’s great is the 25cc 2-cycle gas engine puts both heads to work in such an impressive way.
What we don’t like about the CRAFTSMAN WS205 WEEDWACKER Gas-Powered String Trimmer is the 2-cycle engine meaning that you have to mix fuel and oil to power it.
WEEDWACKER trimmer head
39.4 x 12 x 11 inches
Easy Start technology, 3-step start, WEEDWACKER trimmer head feeds, multi-position adjustable handle
Select a budget-friendly machine like the CRAFTSMAN WS205 String Trimmer and you will not have to spend a lot of money on a performance-oriented garden tool for home trimming and yard neatness.

- Powerful string trimmer with a 4-stroke engine
- Easy and quick start with minimal effort
- Adjustable handle for optimal user’s comfort
- Excellent fuel consumption
- Great value for your money
- On the heavy side
- The lack of a strap
This 4-cycle trimmer by Husqvarna consistently gets great power user or semi-professional ratings for a good reason.
It is not the budget-friendliest option out there, but it is ranked #1 when it comes to the best units offering commercial-grade levels of power and performance at a residential device price.
With the capability to produce a power output of up to 1.07hp, the Husqvarna 324L Straight Shaft Gas String Trimmer can reach more grasses and always function incredibly well.
Though the 4-stroke engine running on pure gasoline saves you the hassle of fuel and oil mixing, it is much heavier than any 2-stroke model and even among the heaviest trimmers in Husqvarna’s lineup.
25cc engine 324L
70 x 9 x 9 inches
Flex drive straight shaft, bevel gear and loop handle, air purge, Smart Start engine and starter

Some of the most worth-praising features of this curved shaft string trimmer by Husqvarna are the Smart Start system for trouble-free start-up and E-Tech II for fewer fume emissions and quieter operation. Not to mention the combi-guard helping users avoid any potential injury while operating this weed eater.

How To Choose The Best Gas String Trimmer
Straight vs. Curved Shafts
- Gas weed eaters are available in either straight or curved shafts.
- Generally, the former is a bit longer and are manufactured to fit into particularly hardest-to-reach spots such as under fences, decks over a patio, or bushes.
- Meanwhile, the latter is lighter and easier to handle & transport and provide greater balance, making them best suited for trimming along your lawns, gardens, sidewalks, and driveways.
- The cutting diameter of gas string trimmers generally varies from roughly 8 to 10 inches (from 20 to 25 cm). The wider the cutting diameter is, the more efficiently it works and the more time spent on trimming you can save. However, the smaller the cutting diameter it is, the more effortlessly it can reach hidden spots that a basic mower can’t quite touch.
- The trimmer line or string trimmer line is a cutting blade.
- Rule of thumb: the tougher and heavier the job, the thicker the trimmer line should be.
- Other features affecting the cutting efficiency and the trimmer line’s longevity are its weight, material, and density.
- Nylon or plastic cord is the most widely used option. Though it is affordable and can spin at a high speed, it cannot withstand the wear and tear of anything but slashing through medium-thick grass and weeds.

- Originally belonging to Sears Holdings and now working under Stanley Black & Decker’s control, Craftsman is a reputable line of work wear, lawn, and garden tools.
Are curved or straight shaft trimmers better?
More adjustable, functional, and generating more torque than curved trimmers, a straight-shaft model accommodates people of different body frames and effectively cuts through tough scrubs, grass, and weeds.
Also, this unit can perform well in more awkward, narrow, hard-to-reach spots around your lawn.
Moreover, it can be compatible with other additional attachments to act as both a trimmer and edger.
Possessing much shorter shafts than a straight-shaft whipper-snipper and staying closer to the surface, curved models are best for shorter people.
Also, female homeowners will find these lighter, more balanced, and easier-to-maneuver trimmers a go-to option.
Are 4-cycle trimmers better?
4-cycle trimmers are much more efficient, eco-friendly, and less noisy than 2-cycle units. But they are more expensive and heavier than a 2-stroke engine.
In short: a 4-cycle trimmer is a better choice for those who want to go completely green or those in search of a device that can run without a gas-oil mixture.
What kind of gas does a 4 cycle engine use?
While a 2-cycle gas trimmer has only a single fuel tank to store the oil & gasoline mixture, a 4-stroke machine keeps the oil and gasoline needed in separate tanks for lubrication.
It means that it self-lubricates while running as long as the oil is kept topped up.
Can you mow your lawn with a trimmer?
You can but shouldn’t. Never use a luxury accessory like a grass trimmer to mow a vast area of grass stretches and bushes.
Despite the extremely sharp blade, since you need to operate it manually, the cutting result of mowing with a trimmer will never be as even as by with a lawn mower.
Instead of pulling up bushes & weeds and cutting the grass verges by hand, why don’t you invest in the best gas string trimmer for spring cleanup or late-summer mowing?
Researching different models by different brands on the market and comparing every single feature from overall quality to affordability and performance, we have compiled this list above. Hope that it can give you an idea which one works best for you.
